13390222 ÷ 851 
We want to divide 13390222 by 851.

Moving on to step 1:
The number 851 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 851

Advancing to step 2:
The number 851 fits into 13 0 times, leaving a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 851

Advancing to step 3:
The number 851 fits into 133 0 times, leaving a remainder of 133.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 133, we get 133.
Grab the next digit (9) from the dividend, add it to 133, then carry on: 1339 / 851

Step 4:
851 goes into 1339 1 times with a remainder of 488.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 851 from 1339 and we're left with 488.
Append the next digit (0) from the dividend to 488 and continue with: 4880 / 851

Let's proceed to step 5:
When dividing 4880 by 851, we get 5 with a remainder of 625.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 4255 from 4880 leaves us with 625.
Fetch the next digit (2) from the dividend, attach it to 625 and continue: 6252 / 851

Let's proceed to step 6:
851 goes into 6252 7 times with a remainder of 295.
Put 7 as the next digit of the answer. 
Result so far: 157.0
The remainder is 295 after subtracting 5957 from 6252.
Bring next digit (2) of the dividend behind the 295 and repeat the process: 2952 / 851

Going ahead to step 7:
851 can be fit into 2952 3 times, resulting in a remainder of 399.
The next digit of our result is 3. 
Result so far: 1573.0
Subtract 2553 from 2952 to get 399.
Fetch the next digit (2) from the dividend, attach it to 399 and continue: 3992 / 851

Moving on to step 8:
851 can be fit into 3992 4 times, resulting in a remainder of 588.
Use 4 as the next digit of our solution. 
Result so far: 15734.0
If we take 3404 away from 3992, we end up with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Moving on to step 9:
When dividing 5880 by 851, we get 6 with a remainder of 774.
Use 6 as the next digit of our solution. 
Result so far: 15734.6
Deduct 5106 from 5880 and we're left with 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

Moving on to step 10:
851 can be fit into 7740 9 times, resulting in a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 15734.69
The remainder is 81 after subtracting 7659 from 7740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 11:
851 can be fit into 810 0 times, resulting in a remainder of 810.
The number 0 becomes the next digit in our result. 
Result so far: 15734.69
If we take 0 away from 810, we end up with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

On to step 12:
The number 851 fits into 8100 9 times, leaving a remainder of 441.
Write down 9 as next digit of the result. 
Result so far: 15734.6909
If we take 7659 away from 8100, we end up with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Step 13:
The number 851 fits into 4410 5 times, leaving a remainder of 155.
The next digit of our result is 5. 
Result so far: 15734.69095
If we subtract 4255 from 4410, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 14:
The number 851 fits into 1550 1 times, leaving a remainder of 699.
The next digit of our result is 1. 
Result so far: 15734.690951
If we subtract 851 from 1550, we get 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Going ahead to step 15:
If we divide 6990 by 851, we get 8 and a remainder of 182.
Record the quotient 8 as the next digit in the result. 
Result so far: 15734.6909518
The remainder is 182 after subtracting 6808 from 6990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Going ahead to step 16:
851 goes into 1820 2 times with a remainder of 118.
Use 2 as the next digit of our solution. 
Result so far: 15734.69095182
If we take 1702 away from 1820, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

The quotient of the division is 15734.69095182, and the remainder is 1.18e-07.
